Same problem here, trying to install lubuntu 17.04 in my old Aspire One and that problem happen anoynly every time. Reading about the problem i found a question about the ACPI, so a decide to turn it off, but Lubuntu doents have the menu options to choose the grup parameters, then to change the boot options of the lubuntu you have to edit the file \boot\grub\loopback.cfg on the pendrive, and add the parameter "acpi=off", near the "boot=casper" i think its a good place.
this is my entry that works
menuentry "Install Lubuntu" {
linux /casper/vmlinuz file=/cdrom/preseed/lubuntu.seed cdrom-detect/try-usb=true noprompt floppy.allowed_drive_mask=0 acpi=off ignore_uuid boot=casper only-ubiquity iso-scan/filename=${iso_path} quiet splash ---
initrd /casper/initrd.lz
}
